Description

Stroller and seat assembly

The related application data

This patent relates to and advocates that the exercise question of application on March 13rd, 2009 is the benefit of priority of the 61/160th, No. 271 U.S. Provisional Application case of " having the stroller (Stroller with Releasable Seat) that can discharge seat ".The mode that above-mentioned related application is quoted is in full incorporated this paper into.

Technical field

The present invention is at stroller substantially, and more particularly relates to the stroller seat, and it has releasing mechanism and the mechanism and can retreading on the stroller, discharge and turning on stroller from stroller of retreading.

Background technology

The stroller performance standard comprises 8 inches ball tests.These test request 8 inch diameter baton rounds can pass through between stroller seat (being generally seat bottom) and passenger seat pallet or child trays when stroller turns forward, and no matter seat tilts still to retread.This requires the set children's of preventing head to be clipped in or to be trapped between pallet and the seat.This may take place under the situation that children entangle with suspender belt inadequately in seat or do not entangle with suspender belt, thereby makes it slide into the pallet below downwards.

Many known stroller and especially U.S.'s family expenses stroller models have the child trays of the frame side that is attached to stroller.Described pallet is crossed stroller frame substantially and is extended in child seat the place ahead, and comprises one or more integrated saucers usually.It is static that pallet keeps when stroller retreads usually.Pallet is independent of the motion of retreading of seat, because on the fixed seat stroller of routine, only the rear surface of seat or back of seat can retread.Therefore, back of seat is independent of remainder, child trays and the stroller frame of seat bottom, seat and moves.This layout must be under the situation in any obliquity by 8 inches balls tests at seat.

Many existing strollers are through providing the part as ride system, and therefore allow infant carrier or infant car seat (ICS) directly are placed on the child seat of stroller.This allows stroller to be converted in essence can to carry originally may be too little or too big and can't be sitting in the stroller of the baby in the special-purpose child seat of stroller.This ICS installs feature and has produced the modularization ride system.The stroller of these types also adopt on the seat the passenger or children's pallet.On these a little strollers, passenger or children's pallet supports the head end of ICS on being positioned over stroller the time.The foot of ICS is supported by armchair structure usually, for example on the seat bottom of the special-purpose child seat by being shelved on stroller.

Many makers have made the stroller and the ride system of similar type.In these strollers some have replaced having the armed lever that extends or passenger's pallet of transverse arm strut member on the place ahead of the special-purpose child seat of stroller.Armed lever supports the head end of ICS usually when being installed to stroller.

Some makers have had the stroller of the special-purpose child seat that retreads with the single-piece manufacturing.In other words, back of seat and seat bottom are united inclination when tilting or retreading.These a little seats also can load and unload or overturn.Yet, known these have this can load and unload a bit or other stroller design of tip-up set in do not have any one to allow ICS directly to be placed on child's seat to make ride system.The stroller of these types is incompatible usually in ICS is installed.

And, in fact on the market at present known all can load and unload or turning stroller seat all uses children's arm rather than child trays.Armed lever appends to seat rather than stroller frame, so that do not disturb seat benefit or replacing, and makes that seat can be by 8 inches ball testing standards mentioned above.Be alternative in armed lever and provide if having the child trays of saucer, it also will be along with seat moves together when seat retreads so.This is because seat bottom and pallet will be united mobile with back of seat.If pallet is installed to seat, so its inclusion will seat orientations and therefore pallet be oriented in and be scattered during change during retreading.If pallet provides and be installed to framework, can solve the problem of being scattered so.Yet the gap between seat and the pallet will change when seat retreads, and therefore influence the ability that stroller satisfies 8 inches ball tests.Be in the space that between seat bottom and pallet, will have little gap under the situation of the position of retreading and therefore be not used in children's leg at seat, perhaps in obliquity, will exist big gap and therefore seat with 8 inches balls tests of impassabitity.Therefore, utilization appends to armed lever that can load and unload seat rather than the pallet that appends to stroller frame in conjunction with these a little seats.Therefore the single-piece of these types seat (no matter be can load and unload, turning maybe can not load and unload and overturn) that retreads does not allow children easily to arrive food/beverage storage place.

And, on market, have some strollers, its have can load and unload, turnover child's seat.These strollers have one or more release actuator usually to be used for release and to remove seat.The representative type release actuator is arranged in the feasible zone that is difficult to lift seat (especially under the situation of seat with children's weight loading).As a rule, release actuator is in the center near how much mid points of seat frame.By contrast, little children's the center head pipe of more close seat substantially.Therefore the seat that carries children has the center of gravity of the head end of more close seat.The hand position combination required with activated releasing mechanism before lifting seat of this weight overbalance makes catches and lifts seat become clumsy and/or difficulty, especially for the situation of children in seat.The extracting of clumsiness on the seat and weight overbalance can be potential make and for the head of a family or caregiver, to be difficult to during removing, keep the seat level from stroller.This can load and unload seat and should not remove or change from stroller when maker was defined in children usually and is in the seat.Yet possible situation is that the customer may ignore this warning and removes under children still are sitting in situation in the seat and/or the children's that overturn the position of taking one's seat.

In this example, release actuator 118 is received in the slit 160 (referring to Fig. 5) of top adaptor union 128 belows.In this example, release actuator 118 is the form of elongate lever.One end of release actuator 118 is pivotally connected to adaptor union 128 at pivot B place.The relativity end 162 of actuator 118 has the grasping edge, and freedom upwards is drawn in the top adaptor union 128 by the grasping edge of squeeze-activated device, pivots around pivot B.Effect end 162 by spring 163 outwards or downward bias to away from top adaptor union 128, and resist the deflecting force that is used to activate of spring and be extruded.Releasing mechanism also comprises release hawser 164, and it has a free end that is coupled to an end of release actuator 118 via the hawser piece.Another free end that discharges hawser 164 has second (not shown), and it is placed in the latch pin 168, thereby hawser is connected to described pin.In this example, latch pin 168 is castellated shafts as shown in Figure 4, and it is placed in the cylinder-shaped sleeve 170 slidably.Inside and outside center hub 126,132 has separately by hub shell 120 boring separately 172,174 aligned with each other, and defines the center shaft H of hub assembly set 106.Sleeve pipe 170 is located along hub axis H and is aimed at.Sleeve pipe 170 is placed in the wall 176 on the inside, but to the outside to the surface of inner center hub 126.Hub axis H is usually perpendicular to frame attacher 128,130.

As shown in Figure 5, discharge hawser 164 and be routed to the outside from an end of actuator 118, but inwardly towards the surface 180 of the inside center hub 126 of hub shell 120.Surface 180 can be crooked, so that smoothly, little by little guide hawser 164 from actuator towards boring 172.As shown in Figure 6, sleeve pipe 170 has the insert 182 that is received in the end that is adjacent to surface 80.Insert has the crooked surface 184 that enters, and its profile is harmonious but is substantially funnel-form.The surface 184 of insert 182 directs into hawser 164 in the boring, and does not form quirk in hawser, and with hawser from re-routing and parallel axes and conllinear perpendicular to the hub axis in fact.As shown in Figure 5, a pair of hawser guide member 186 is spaced apart along the surface 180 on the outside of inside center hub 126.Guide member 180 separates each other, bending, and moves and assemble each other towards hub axis H.Guide member 186 is away from surface 180 and help to discharge hawser 164 and be directed to boring from actuator, and helps to keep the release hawser to aim between these two points.

As shown in Figure 4, releasing mechanism also has the spring 188 that is contained in the sleeve pipe 170.Spring 188 makes latch pin 168 outwards partially towards positive seat bearing 142, and generally the tabular surface 138 from the cloudy seat bearing 134 is outwards outstanding to make it.Latch openings or the receiver 190 that provides and aim at hub axis H by positive male part is provided sun seat bearing 142.When seat assembly 100 was installed to frame assembly 51, cloudy seat bearing 134 was reduced in the positive seat bearing 142.Latch pin 168 will be along the slope 152 be advanced, and inwardly shifts onto in the cloudy seat bearing 134 or towards cloudy seat bearing 134 and promote, thereby allows to connect sun and cloudy seat round.

Fig. 7 shows the cut-out of the seat hub assembly set 106 that comprises seat bearing and releasing mechanism assembly to Fig. 9.As shown in Figure 7, when cloudy seat bearing 134 was placed on the positive seat bearing 142 fully, spring 188 started latch pin 168 and enters in opening or the receiver 190.This is latchable to frame assembly 51 with seat assembly 100.

Can be easily discharge and remove seat assembly 100 from frame assembly 51.The user only needs on the direction of the effect end 162 of grasping release actuator 118 and the arrow Q in Fig. 5 upwards or inside squeeze-activated device enters top adaptor union 128.Actuator 118 will pivot around pivot B.The location that is connected to actuator that discharges hawser 164 causes spurring hawser downwards when release actuator 118 is upwards pushed.Hawser 164 will resist the deflecting force pulling latch pin 168 of spring 188 subsequently, and from as shown in Figure 8 opening or receiver 190 the release bar lock pin.When the opening 190 in the positive seat bearing 142 of latch pin 168 removings, seat assembly 100 freely promotes from frame assembly 51, as describing among Fig. 9.

In the example that is disclosed, location, a distance, position of the attachment point of release actuator 118 between distance seat assembly 100 and frame assembly 51.Release actuator 118 also be configured in one way make the user can squeeze-activated device discharging seat assembly 100, and continue to keep its to the grasping of seat assembly to promote seat assemblies from frame assembly 51.The user need not operated actuator to discharge seat assembly, discharges its grasping, and subsequently at another location grasping seat assembly so that remove seat assembly from frame assembly.Disclose herein and therefore the design of described releasing mechanism and location allow simple and easy seat release gimmick.Described design also allows the designer roughly at location, the center of gravity place of seat releasing mechanism, thereby considers user children when frame assembly discharges seat and can be sitting on the seat.The releasing mechanism that is disclosed need not to be positioned at the position of chair mounted point.But releasing mechanism can be positioned on and need overlap with the seat center of gravity and/or need provide during use the stable grasping of seat assembly and the place of fixing.

Fig. 7 also shows the sectioned of fold joint point 56 on the left of assembling to Fig. 9.Among these figure each is showed the assembly in the configuration set up as the stroller among Fig. 1 and Fig. 2.As mentioned above, at exercise question be " collapsible stroller and folding mutual interlocking gear (Foldable Stroller and Fold Interlock Mechanism) " the 12/410th, No. 243 and exercise question are details, feature and the aspect of more detailed description fold joint point in the 12/610th, No. 902 common U.S. patent application case co-pending of " collapsible stroller and be used for its fold linkage (Foldable Stroller and Fold Linkagefor Same) ".In an example, stroller 50 can adopt optional seat or folding interlock.Described device can stop seat assembly 100 on stroller, up to frame assembly open fully and be in set up and breech lock configuration in till.Described device also can stop the release of frame assembly 51 when seat assembly 100 is installed to frame assembly and fold.

To Fig. 9, when seat assembly 100 was installed on the stroller 50, folding latch finger 200 can't discharge, and frame assembly 51 can't fold in this example referring to Fig. 7.In this example, the tabular surface 138 on lock pin 202 and the cloudy seat base 134 serves as the part of interlock mechanism separately.Lock pin 202 and face 138 can be cooperated each other, to prevent to activate folding breech lock by latch finger 200 (see figure 7)s are locked in position latching.By frame assembly 51 is in configuration is set, and seat assembly 100 is installed to fold joint point 56, the tabular surface 138 on the cloudy seat base 134 leans against on the contact jaw 204 of pin 202.It is pushed outwards moving that pin is being resisted the bias force of selling spring 206.In this lock-out state or position, pin 202 keyed end 208 is aimed at hole or recess 209 in the latch finger 200, and passes hole or recess 209 and in place.Be installed at seat assembly 100 under the situation of stroller, latch finger 200 can't move.Even the user will attempt activating folding actuator 90 (see figure 1)s (it will strain hawser and latch finger 200), the keyed end 208 of pin 202 also will prevent moving of latch finger.

In this example, for folded frame assembly set 51, the user must at first remove seat assembly 100 from stroller 50.In order to do like this, the user is pulled upwardly release actuator, and seat assembly is mentioned from frame assembly 51.When the tabular surface 138 of cloudy seat base 134 is skipped the contact jaw 204 of corresponding lock pin 202, pin spring 206 will be launched the promotion lock pin, make it inwardly pass shell cover 144.The keyed end 208 of pin 202 then withdraws from hole or recess 209, and latch finger 200.Show this unlocked state or position among Fig. 9.

Break away from pin 202 under the situation of latch finger 200, the user then freely handles folding actuator 90 with the folded frame assembly set.Although this paper does not describe, when frame assembly was in folded configuration, the part of fold joint point 56 may hinder lock pin 202 to turn back to latched position.In this example, be at frame assembly 51 under the situation of folded configuration, seat assembly 100 can't be reinstalled.Interlock pin 202 is held and stops the unlocked state inwardly outstanding from shell cover 144, thereby prevents the attached of cloudy seat base 134.The contact jaw 204 of lock pin 202 will stop cloudy seat base 134 to be attached to positive seat base 142.Frame assembly 51 must at first be deployed into the configuration that is provided with among Fig. 1, and then folding breech lock must be latched.In this example, frame assembly 51 can comprise the storage breech lock.As shown in Fig. 1 and Fig. 2, can use conventional storage breech lock that frame assembly 51 is remained in the folded configuration.For instance, the storage breech lock can comprise plastics flexible latch or locking arm 212, its be installed to rear support leg 58 and from the locking pin 214 that cooresponding front leg strut 62 stretches out one.When frame assembly was folding, locking pin 214 can be manually or automatically meshed in gripping arm 212, and can be by manual releasing, so that launch frame assembly, as known in the art.

When stroller frame 51 launches and latch finger 200 when latching, hole in the latch finger 200 or recess 209 are aligned with each other as among Fig. 9 once more with pin 202.Yet by means of the power of pin spring 206, pin 202 still remains in the unlocked position.Cloudy seat base 134 can drop on the positive seat base 142.The button-head 216 of lock pin 202 will lean against on the inclined-plane 140 at bottom place of tabular surface 138 and 140 straddle along the inclined-plane, and then descend with seat assembly 100 and straddle on described.Inclined-plane 140 and face 138 will drive the bias force of stop pin 202 antagonistic springs 206 and get back in the shell cover 144, and this is driven into keyed end 208 in the hole 209 of latch finger 200 again.Seat assembly 100 and interlock mechanism will prevent once more that fold joint point 56 is unlocked.Discuss as mentioned, in this example, before seat was removed once more, frame assembly 51 can't fold.

The interlock mechanism that is disclosed be need not in conjunction with as stroller seat assembly 100 disclosed herein and the optional feature utilized.Perhaps, described interlock mechanism can be different with the example that this paper shows and describes, and will understand after reading the present invention as the those skilled in the art.

Referring now to Fig. 4, Fig. 5 and Figure 10, to Figure 13, the stroller seat assembly that is disclosed also has the adjustment capability of retreading.Can utilize the hereinafter described mechanism of retreading to adjust to comprise the leaning angle of the whole seat assembly 100 of upper frame portion 102 (comprising not shown back of seat) and lower frame part 104 (comprising not shown seat bottom) interior interior.

The inside of interior center hub 126 (except outer side) has a pair of hawser track 220 that retreads that is formed at wherein.The opening 222 that enters on the lagging dege of center hub 126 is communicated with inlet hawser track 224.As best illustration among Figure 10 and Figure 12, inlet hawser track 224 is divided into two hawser tracks 220, and it then diverges on relative direction each other.In this example, each in the track 220 and 224 is formed by the isolated moulded ribs 226 that the inside face from interior center hub 126 stretches out.

Similarly, the inside of outer center hub 132 (except interior side) also has a plurality of moulded ribs 228.The number of these ribs 228 helps to reinforce the structure of the structure of hub assembly set 106 in the time of can being configured to be formed on assembling.Yet the some ribs in these ribs are through being configured to form two groups of recesses 230 that retread especially on the inside face of center hub 132.As best illustration among Fig. 5 and Figure 11, locate toward each other the inside that described two groups of recesses 230 are crossed outer center hub 132 usually.Each group 230 comprises three contiguous recess 232a, 232b and 232c, and its corresponding recess with relative group is relative.Described relative recess to 232a through directed and be configured so that seat assembly 100 is positioned in the complete stand up position.Described relative recess to 232b through directed and be configured so that seat assembly 100 is positioned in the position of partly retreading.Described relative recess to 232c through directed and be configured so that seat assembly is positioned in the position of retreading fully.As be appreciated by those skilled in the art that, only use two pairs of relative recesses that two positions of retreading can only be provided, can use maybe that the recess that discloses provides the position of retreading more than three more than three pairs.

In the example that is disclosed, described group of recess 230 each can through form with towards hub axis H radially towards interior.In this example, as best illustration among Figure 11, described recess is angled or skew with respect to the axis that radially extends from hub axis H.Similarly, as best illustration among Figure 12, described also angled or skew with respect to the axis that radially extends from hub axis H to hawser track 220.The deviation angle that is disclosed can be assisted and be reduced to be used to activate the angle of bend of hawser of mechanism of retreading.As shown in Figure 10, the hawser 234 that retreads extends along each the inside in the rear frame legs 108 of upper seat chair frame 102.Although do not show that herein the far-end of the hawser 234 that retreads is connected to the actuator 236 that retreads (seeing that Fig. 1 is to Fig. 3), the actuator 236 that retreads is carried on crossing on the parts 109 of upper seat chair frame 102 tops.In this example, the actuator 236 that retreads has the oar 237 that can pivot forward, and its rolling-in when rotated discharges hawser 234.In another example, release actuator can be the extrusion pressing type actuator that is expressed to simply in the seat frame, and can be the rotary-type actuator that reverses around the axis that crosses parts 109.Retreading actuator 236 can be in configuration and structure and function aspects variation as set.The actuating of actuator 236 of retreading only need be strained the hawser 234 that retreads.

As shown in Figure 12, the near-end of each hawser 234 that retreads is divided into a pair of cable end 238.Each cable end 238 stops at latches block 240 places.In the near-end of hawser 234 of retreading enters through inlet 222 in the center hub 126 (or inside of hub shell 120) and along entrance track 224 and route.Cable end 238 is the route along separating corresponding one in the hawser track 220 then.When assembling during hub shell 120, corresponding in center hub 126 and outer center hub 132 inside face towards each other, with the formation closed cavity.Yet center hub 126 and 132 can relative to each other rotate around hub axis H.Any a pair of recess 232a, 232b or 232c of retreading can aim at hawser track 220 by rotation mode.Retainer (not shown) can be provided on any one or both in center hub 126 and 132, to limit two center hubs rotating distance relative to each other.In an example, these a little actuators can be integrally molded as the part of rib mentioned above 226 and/or 228.

In the cable end 232 each has the biasing element that is late spring 242 forms that is positioned at corresponding hawser track 220.Spring 242 makes latches block 240 at the upper offset of direction radially outward away from hub axis H.Spring 242 through arranging so that the recess of piece 240 when being biased to described block alignment right one in.But the biasing of user's antagonistic spring 242 and activate the actuator 236 that retreads, so that the hawser 234 that retreads is along upwards withdrawal of rear frame legs 208.Hawser 234 will make piece 240 radially inwardly and withdraw from from recess again.This has discharged the mechanism of retreading, to allow the back skew adjustment of seat assembly.When recess during to 232a, 232b or 232c and block alignment, and when the actuator 236 that retreads is released, spring 242 will be launched pushing block 240 and radially outward enter recess among one among 232a, 232b or the 232c.

In the example that is disclosed, when cloudy seat base 134 was attached to positive seat base 142 on the fold joint point 56, outer hub portion 122 was fixed with rotation mode.Therefore, when seat simply 100 when being installed to frame assembly 51, described group of recess 230 also fixed on the position or with rotation mode.Therefore when the skew adjustment seat assembly 100 of back, interior hub portion 124 rotates with respect to outer hub portion 122 around hub axis H.Yet, when with seat assembly 100 when frame assembly 51 removes, hub portion 122 and 124 both together with seat assembly separately from frame assembly 51.

In the example that is disclosed, saucer 112 is installed to outer hub portion 124.Therefore, when seat assembly 100 was installed, saucer 112 was also fixed with rotation mode with respect to frame assembly 51.Figure 13 shows that seat assembly 100 is in complete stand up position, and latches block 240 will be arranged in the recess 232a that retreads by this.Figure 13 also shows that with mirage seat assembly 100 is in the position of retreading fully, and latches block 240 will be arranged in the recess 232c that retreads by this.No matter the leaning angle of the seat assembly 100 in the revealed instance how, saucer 112 all remains on the orientation of same grade.The adjustment of the back bevel angles of seat assembly can not influence, changes or change the angle of saucer 112.

Saucer 112 can partially or entirely be integrally molded as the part of outer hub portion 124.Perhaps, saucer 112 can comprise pedestal, carriage or ring, hub portion 124 outside it is fastened to when assembly is assembled.In this example, saucer 112 can be randomly for can optionally removing or dismantle from seat assembly 100.Perhaps, point of connection can be Unitarily molded or be attached to outer hub portion 124, and described point of connection is configured to removable saucer structure is connected to hub portion.This point of connection also can be configured admits except that saucer other to install, or is connected with other device except that saucer, as indicated above.In an example, the point of connection that is used for the saucer on the outer hub portion 124 in this example can be configured so that in removable mode the ICS adapter is attached to stroller.In an example, positive seat base 142, cup holding ring 244 and saucer receiver 246 can form through assembling to form three unitary part of saucer 112.In another example, positive seat base or outer center hub 132 can be formed with support ring 244 and the receiver 246 through integrating.Perhaps, receiver 246 can be the independence molded part of snap fit in the support ring 244.Support ring 244 can separate with positive seat base 142 or outer center hub 132, and with screw rod or other fastener or come attached via the buckle type feature.

The seat assembly that discloses be that saucer 112 keeps the parts as seat assembly 100 on the other hand.Therefore, when removing or during tip-up set assembly set (represented in as Fig. 2), but saucer still abutment chair holder use.In addition, no matter seat tilts or the position of retreading, saucer will be still be installed in upset or towards after direction on seat mutually neat.

On the stroller of disclosed herein and description, seat assembly 100 is removable and turnover.Therefore, seat assembly also can be used as individual unit and retreads.Therefore, can provide armed lever on the seat, and armed lever can rotate with seat, therefore not influence 8 inches ball testing standards mentioned above.If provide the pallet with saucer to replace the armed lever on the seat assembly of disclosing, so described pallet also need retread and pivot with seat, so that observe 8 inches ball testing standards in any seat position.This will cause and the content of the container of institute's fixing in the saucer might be splashed on pallet.Along with seat retreads, pallet may rotate about 30 ° (for example) with seat assembly, thereby its content might be splashed on one's body the children.In this example, pallet can be attached to the non-moving part of stroller, for example framework potentially.Yet because the bottom part (seat bottom) of seat retreads together with the remainder of seat, and pallet will be across the width of seat, and therefore when seat retreads, 8 inches ball tests difficulty (if not impossible words) are passed through.

If possess the armed lever with seat assembly 100 rotations, the stroller in this example will be incompatible with ICS so.Therefore, such stroller (if the part of ride system has ICS) can be sold with independent ICS adapter, and described ICS adapter will replace child's seat assembly 100 to use when it is removed.Child's seat assembly must remove from stroller frame fully, and by replacing in order to the ICS adapter that ICS is installed to stroller.Because the cause of the geometry of removable, turnover child's seat, making child's seat assembly be fit to ICS is directly installed on may be also infeasible on the stroller seat, because whole seat may retread.Yet existing ride system client may be familiar with the ride system stroller that allows ICS to be placed directly in child's seat assembly and be coupled to pallet or armed lever.This precedent may cause the potential misuse to stroller and ICS, because the existence of armed lever in this example or pallet may cause client to believe that they can be placed into ICS in child's seat assembly safely.

In the example that is disclosed, be used for avoiding aforementioned potential problem by eliminating making of armed lever or pallet fully.Instead, seat assembly 100 comprises the saucer 112 on the either side that is positioned at child's seat.These saucers 112 are attached to the fixedly male connector part of the hub assembly set 106 on the seat assembly outside, as describing among Fig. 1 to 3.Male connector is attached to seat, and removes with seat.Yet when this part of hub assembly set 106 was attached to stroller, it was maintained fixed, with the seat location independent that retreads.Seat assembly can retread, and saucer keeps level or mutually neat, and is as indicated above.In addition, because the front portion of seat assembly is open, and not hindered by child trays or armed lever, therefore the stroller that is disclosed and seat assembly have also been eliminated and mentioned above have been tested relevant problems with 8 inches balls.In addition, in case children's age even as big as entering/withdraw from stroller independently, children needn't remove child trays or armed lever in order to enter or to withdraw from seat and deal with.In addition, in this example armed lever or child trays do not exist also stop client that ICS is directly prevented on child's seat assembly 100 or in.Owing to do not have the structure of being familiar with of the head end that can obviously support ICS, so the possibility that client can be placed on ICS on the stroller depicted in figure 1 mistakenly is less.For client, ICS can be supported by seat assembly on the stroller 50 100 or frame assembly 51 wherein suitably will be more not apparent.

And the representative type child trays comprises bigger, heavy molded plastic structure usually, and it needs a lot of resin materials to make.Armed lever is generally comprised within the attaching parts end and has the shaping of mechanical device and the metal tube that polished.Therefore armed lever and pallet will cause bigger assembly cost and complexity usually.Comparatively speaking, the saucer solution that is disclosed may be simple many and have more the cost effect.Described part can be all-plastic, utilize less resin, and can realize the present invention not need complicated mechanism or part through design.

In the another aspect of the present invention that is disclosed, the seat release actuator 118 of releasing mechanism is placed on seat attachment point top.In this example, release actuator is elongated, and the grasping easily by the hunting range below that is placed on seat frame pipe geometry.This seat geometry forms easily, and the grasping seat frame activates the structure of release actuator 118 simultaneously so that it is mentioned from stroller frame.Release actuator 118 is located near the head end of seat frames.Therefore, these grasp-point are aimed near seat and children's's (when described children take one's seat on the seat) center of gravity.This can make seat balance more during removing.If children do not take one's seat on the seat, seat will be very light so, and only the center of gravity of seat will be mentioned and the ability of carrying described seat has very little influence effectively to the user.

About the seat mechanism of retreading, it may be the retread hawser 234 and discharge hawser 164 of seat that how to connect up that a challenge of this type of compression arrangement is provided at seat hub assembly set 106 places.In revealed instance, the both sides of retread hawser 234 and corresponding seat release actuator (see figure 10) are in line and extend between described both sides.The downside of upper frame adaptor union 128 can possess hawser guide member or groove 250, and it is clipped between each side of described release actuator.Therefore the hawser 234 that retreads is not situated between with release actuator 118 and hawser 164 and connects.Therefore, the hawser 234 that retreads is walked around release actuator 118.

In this example, the interior section of each seat hub assembly set is filled with the mechanism assembly that retreads in batch.Therefore therefore, release actuator is by means of being connected to seat latch pin 168 from the vertical pulling hawser of actuator.Hawser 164 routes to the outside of seat hub assembly set 106, does not connect so that be not situated between with the functor that retreads.This realizes simple relatively mechanism.Because latch pin 168 be positioned to retread or hub pivotal axis H coaxial, so the position of retreading of seat can not influence the functional of releasing mechanism.In this example, discharge alternately the connect up independent guide member that passes the identical opening 222 that is adjacent to the hawser 234 that retreads or can be provided in the hub of hawser and route to the center shaft H of hub.

Known or existing stroller adopts removable seat sometimes.In each, be used for fixing and remove seat mention a little or grip locations around the center of seat.If children sit in the seat, grasp-point will fully depart from the center of gravity of occupied seat so.A kind of known stroller adopts band of material that seat is mentioned from stroller.Described circle is loose or flexible, and is positioned the top, center of described seat, and therefore can be positioned the center of gravity place near seat under children sit in wherein situation.Yet described circle does not provide the highly stable or crash-resistant grasping to seat, especially under the situation of the occupied certificate of seat.

The seat assembly that discloses through being described as having the upper and lower seat frame.But these framework supports fabrics are with regard to seating face, described fabric back of seat and the seat bottom that delimited suspends from described framework of taking one's seat.Plastics also can be installed to described seat frame with regard to seating face and have and be positioned at the take one's seat fabric cover of surface of described plastics.Perhaps, seat frame can form the integral part of back of seat or seat bottom or eliminate together within the spirit and scope of the present invention.The seat frame term therefore in this article broadly in order to refer to top seat part, lower seat part, back of seat, seat bottom, with regard to holder structure etc. and should be considered as and its synonym.

Hub assembly set 106 is through being described as having inner cloudy installation component and outside positive installation component.These assemblies can be put upside down within the scope of the invention.And installation component can be different with the example of showing herein and describe with structure.Similarly, having used specific components shape, configuration, structure and layout to describe discharges and the mechanism of retreading.These also can be different with the example that is disclosed within the spirit and scope of the present invention.Release actuator 118 can be the extrusion pressing type button, and it moves to linearly in the seat frame but not pivots around an end.Perhaps, actuator 118 can rotate with the release bar lock pin around the axle of seat frame pipe.Latch pin can be substituted by other suitable bolt lock mechanism or device, but so that keeps seat assembly to be attached to frame assembly with delivery mode.Retreading mechanism's (comprising wireline deployed arranges with recess) also can be different with the example that discloses and describe herein.Can change the wiring of various hawsers equally.

Though teaching according to the present invention has herein been described some stroller, seat assembly and assembly thereof and feature, covering scope of the present invention is not limited thereto.On the contrary, all embodiment that belong to the teaching of the present invention in the scope that can permit equivalent are fully contained in the present invention.
